Payment connection error with PayPal

Hi @tderouindesign ,

Thank you for reaching out.

We currently have an internal bug report of the notice below (TECTRIA-74). However, this should not have an effect with connecting to PayPal.

Deprecated: md5(): Passing null to parameter #1 ($string) of type string is deprecated in /home/petbar51/monsonartscouncil.org/wp-content/plugins/event-tickets/src/Tickets/Commerce/Cart.php on line 154

I suspect something is blocking the?WordPress REST API here, and is causing the issue. If you have some security plugins (i.e. Wordfence), ensure that its settings is not blocking the REST API. I would also recommend checking with your WebHost as some?mod_security?configuration could potentially attribute to the failure.

Hello @tristan083 ,

I tried to resync the connection and then checked the Wordfence live traffic page to see if an action made by the Event Tickets plugin was blocked after receiving the same errors.

No block was listed in Wordfence.

I also switched over to Learning Mode in Wordfence and the attempt to resync still failed.

In addition to Event Tickets we also have Gravity Forms installed and the connection between PayPal and Gravity Forms is working just fine. I also disabled the connection to PayPal in Gravity Forms in case that was causing the error but the resync between PayPal and Event Tickets still failed.

This seems to be more related to the plugin not being completely compatible with PHP 8 and greater.

Thoughts?

Hi @tderouindesign ,

Thank you for your message and for taking the time to action on my recommendations.

The issue seems to be isolated and not happening across the board, as we have users using PHP 8.x with Event Tickets and having no issues connecting to PayPal.

I suspect there’s a conflict that’s causing the issue here. It would be good to test for conflicts. Could you follow the following steps?

1. Deactivate all other plugins except for The Events Calendar Plugins.
2. Switching to the Default theme.

Please read the Testing for Conflicts Article before doing anything. 

To be safe, we’d recommend conducting tests and updates on a Staging Server. Also, please keep a working backup of your website.

Hi @tderouindesign

I hope you’re doing well. I just wanted to touch base and check in with you. It’s been a little while since we’ve heard from you. I was just curious if you had the chance to try out the recommendation provided above.

Let me know if there’s anything I can assist you with.

Hi there,

It appears that we haven’t heard back from you in a while, so I’ll assume that the matter has been resolved. If you need any more help, feel free to start a new thread and we’ll be happy to assist you.

@tristan083

As noted in my initial post… we already deactivated all plugins and tried a default WordPress theme without success.

Not sure there is any other course of action to take here but I am willing to try if you have any other suggestions. Thanks!

Hi @tderouindesign

Sorry for not getting back to you earlier. Have you considered downgrading your PHP to version 8.0 or 7.4 to see if it resolves the issue?
